Ahh, so this is the problem with glamor. |
| 59 |
I've already figured out the way how to specify module loading order. |
| 60 |
However I couldn't solve the radeon driver load problem with full relro. |
| 61 |
My efforts weren't enough. Although I haven't considered fb module. So |
| 62 |
I'll give it another try. And also retest glamor. |
